Specification of Letters Patent.

Patented July 8, 1913.

Application filed December 20, 1911. Serial No. 667,027.

To all whom it may concern Be it.known that We, CLARENCE SEYMOUR GREEN and ALFRED Connors, citizens of the United States, residing at Marlcopa, in the county of Kern and State of California, have invented a new and useful Vehicle- Spring, of which the following is a specipear hereinafter.

fication.

One object of the present invention is to lessen the expansion and contraction of the steel in vehicle springs.

Another object of the invention is to make the spring more pliable in its action.

A further object of the invention is to absorb the jar of rebound.

Other objects of the invention will ap- The accompanying drawings illustrate embodiments of the invention, and referring thereto: Figure 1 is a plan of the spring, partly broken away. Fig. 2 is a side elevation thereof. 'Fig. 3 is a section on line c -a in Fig. section of the spring. Fig. 6 shows a modix"-a: in Fig. 2. Fig. 4 is a section on line Fig. 5 is a partial vertical fied form of connecting the spring leavesat the center thereof.

Referring to Figs. 1 to the spring is composed of two series of leaves or members,

overlapping at the center of the spring, and

extending outwardly from said overlap ing portions at each side, and curved to orm in conjunction, aserni-elliptic or similar spring. Said series of spring members at each side may comprise an upper" leaf '1,

tions are. in contact as shown at 8 and are secured in such contact by clamping means 5 and 6. @By reason of the spaces 7 aforesaid between" adjacent leaves, the pliability of the springs is increased. The semi-elliptic spring built. up in this manner may be used in the same manner as the usual semielliptic spring, either in conjunction with other springs or by itself.

As shown in Fig. 5, each. of the spring leaves may be connected to the leaves above and below the same by pins or teats 20 on the leaves, extending into slots 21 on the adjacent leaves, and by lugs or lips 22 extending upwardly from each spring, and embracing the overlying spring, or either of these connecting means may be used without the other. At the center of. the spring the leaves may be formed with n-hole or slot as shown in Fig. 3, for receiving the bolt, 01' as shown in Fig.6,each 'leaf may be pro vided with a conical portion 23 engaging with corresponding conical portions in the next higher leaf, these conical portions being bored to receive the bolt.

It will be understood that the invention is applicable to any style or shape of spring, to any thickness and to any width of spring leaves, and to any number of leaves.

An important advantage of the invention is that it lessens the crystallization of the steel used in the springs.

What we claim is:

1. A vehicle spring, comprising two's ries of leaves overlap ing and in contact at their inner ends, an converging so as to be in. contact at their outer ends, and means for clamping the overlap ing inner end portions of said leaves toget er, each spring lieing'spaced from the adjoining leaf on the same side by the overlapping portion of the leaves of the series on the oppositet'si'de.

i 2. A vehicle spring, comprising two series of leaves overlap ing and in contact at their inner ends, an converging so as to be in contact at their outer ends, means for clamping the overlapping inner end portions i set our hands at Maricopa, California, this of said leaves together, each spring being '12 day of December, 1911.

spaced from the adjoining leaf on the same w side by the overlapping portion of the leaves GREEN of the series on the opposite side, and

clemping means at the outer portions of In presence of said leaves, securing such portions together. H. A. PETERSON,
